I’ve long been a fan of the open-source LibreOffice suite. It works well, it’s free, and it does everything I’ve ever needed an office suite to do. The latest edition, LibreOffice 6.3, is better than ever. It may also be your best choice for a standalone desktop office suite in the years to come.
You see, Microsoft doesn’t want you to buy its next office suite: Office 2019. No, I’m not making that up.
